Light Bulb Intensity Formula at Karen Strickland blog

Light Bulb Intensity Formula. Using l for luminosity, the intensity of light formula becomes i=la i = l a. If you are using light bulbs with a wattage marked on them, such as 60w for 60 watts, that's how much electrical power the light bulb uses. It states that the intensity per unit area varies in inverse proportion to the square of the distance. Divide the relative intensity of the bulb by this power to find out how efficient the bulb $n$ is the number of photons; I = p/ (4 π d²) where p is the power of light emitted at the filament and d is the distance from filament to the surface of the bulb. The lumen (unit lm) gives the total luminous flux of a light source by multiplying the intensity (in candela) by the angular span over which the light is emitted. Distance is measured to the first luminating. Because light waves spread in all directions, to accurately calculate light intensity, the denominator. One formula for light intensity is $$ i = \frac{nfh}{at} \,,$$ where:
